Understanding Mānuka honey
Mānuka honey is made in New Zealand by bees that collect nectar from the native Mānuka plant. It is known for its distinctive flavour and naturally occurring methylglyoxal, usually shortened to MGO.
How MGO is measured
An MGO rating shows the measured concentration of methylglyoxal in honey in milligrams per kilogram (mg/kg). A higher number means more MGO was recorded in the test. It does not describe a recommended use or a scale of health benefits.
How New Zealand Mānuka honey is defined
For honey to be exported as New Zealand Mānuka honey, it must meet the scientific definition set by New Zealand's Ministry for Primary Industries (MPI). Testing looks for four chemical markers and one DNA marker. MGO is a separate rating and does not establish that definition on its own.
Read the MPI guidance on Mānuka honey testing.
Taste and texture
Mānuka honey can have a rich, smooth texture with distinctive earthy and floral notes. Its colour and texture can vary naturally from one batch to another.
Choosing Mānuka honey
When comparing Mānuka honey, look for a clearly stated origin, MGO rating, batch-testing information and laboratory report references. These details make it easier to understand and compare what you are buying.
